Benefits of technology

[0010] The foregoing and / or other aspects of the present general inventive concept may be achieved by providing a hydrophobic treatment method of forming a nozzle plate used with an ink jet head capable of preventing a hydrophobic layer from being formed on an unintended region.

Problems solved by technology

As a result, a printing quality deteriorates due to distortion of an ejecting direction of the ink and reduction of an ejecting speed of the ink, and a meniscus formed after the ink has been ejected also becomes unstable.
However, the methods of forming the hydrophobic layer on the nozzle plate have a problem required to be improved.

Embodiment Construction

[0018] Reference will now be made in detail to the embodiments of the present general inventive concept, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The embodiments are described below in order to explain the present general inventive concept by referring to the figures.

[0019] FIGS. 1 to 3 are cross-sectional views illustrating a hydrophobic treatment method of forming a nozzle plate used with an ink jet head according to an embodiment of the present general inventive concept.

[0020] Referring to FIG. 1, first, an ink jet head can be provided. The ink jet head may use an electro-thermal transducer as a pressure-generating element for ink ejection. However, the present general inventive concept is not limited thereto, and it may be widely applied to an ink jet head provided with a nozzle plate and a nozzle formed on the nozzle plate to eject ink. Hereinafter, a method of fabricating an ink jet...

Abstract

A hydrophobic treatment method of a nozzle plate used with an ink jet head includes preparing an ink jet head provided with a nozzle plate having a nozzle for ejecting ink, and forming a hydrophobic layer on the nozzle plate, the hydrophobic layer being formed of a silane compound containing a terminal functional group transformed to a hydrophilic functional group using a photochemical reaction. The silane compound is selectively exposed. In the hydrophobic treatment method, both a hydrophobic surface and a hydrophilic surface may be formed on one material layer.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Patent Application No. 2004-31128, filed May 3, 2004, the disclosure of which is hereby incorporated herein by reference in its entirety. BACKGROUND OF THE INVENTION [0002] 1 . Field of the Invention [0003] The present general inventive concept relates to a method of fabricating an ink jet head and, more particularly, to a hydrophobic treatment method of forming a nozzle plate used with an ink jet head. [0004] 2 . Description of the Related Art [0005] An ink jet recording device functions to print an image by ejecting fine droplets of printing ink on a desired position of a recording medium. Such an ink jet recording device has been widely used due to an inexpensive price and characteristics capable of printing numerous kinds of colors at a high resolution. The ink jet recording device basically includes an ink jet head for substantially ejecting the ink and an ink container in fluid communi...
